2-[(E)-2-Phenylethenyl]thiophene CAS 3783-65-1 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 2-[(E)-2-Phenylethenyl]thiophene (CAS 3783-65-1), a certified reference material (molecular formula C12H10S, MW 186.27 g/mol) for analytical method development and quality control.

Structurally, 2-[(E)-2-Phenylethenyl]thiophene (C12H10S) contains sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 186.27 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 2-[(E)-2-Phenylethenyl]thiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
